Container equipment is labeled HL and HHL
Thread Content
May I ask the experts what HL=300mm and HHL=400mm mean in terms of container equipment?
High liquid level limit and high-high liquid level limit?
HL=300mm: Indicates a high liquid level of 300mm. HHL=400mm: Indicates an extremely high liquid level of 400mm. There are levels of high and extremely high; these are the interlock values and alarm values set according to process requirements.
HL denotes high liquid level, while HHL denotes very high liquid level; there are levels of high and very high. These are the interlock values and alarm values set according to the process requirements. The design should also include LL for low liquid level, and LLL for very low liquid level. They are all used for level control
You’re so amazing; how is it that you think the same way as I do? Hehe, do you remember what day it is today? Hehe
